about ubiquitous ordinals
What are ubiquitous ordinal?
Well, you know that ORD, is, the order type of ordinals,
and so it's an ordinal, of all the ordinals.
Is a ubiquitous ordinal a finite ordinal?
I would appreciate a "yes" or a "no" in your response.
The ubiquitous ordinals are, for example,
a theory where the primary elements are ordinals,
for ordering theory, and numbering theory,
which may be more fundamental, than set theory,
with regards to a theory of one relation.
It's like the universe of set theory,
Do you and I mean the same by "universe of set theory"?
I am most familiar with theories of
well.founded sets without urelements.
In the von Neumann hierarchy of hereditary well.founded sets
V[0] = {}
V[β+1] = 𝒫(V[β])
V[γ] = ⋃[β<γ] V[β]
V[ω] is the universe of hereditarily finite sets.
For the first inaccessible ordinal κ
V[κ] is a model of ZF+Choice.
For first inaccessible ordinal κ
[0,κ) holds an uncountable ordinal and
is closed under cardinal arithmetic.
There is no universe in ZFC, don't be saying otherwise.

About triangles and right triangles,

like ZFC with classes, now your theory has
classes that aren't sets.
Yeah, my mathematical conscience demands that

It is wrong to treat claims about right triangles
as though they are claims about more than right triangles.
Definition usually expands,
The hypocrisyᴿꟳ of NOT expanding
the definition of right triangle ABC
to encompass triangles without right angles
leaves it NOT wrong that
a segment CH from right angle C
perpendicular to and meeting side AB at H
makes two more triangles ACH BCH,
which are both similar to ABC
which, as similar triangles,
have corresponding sides in the same ratio
so that
A͞H/A͞C = A͞C/A͞B
H͞B/B͞C = B͞C/A͞B
(A͞H+H͞B)⋅A͞B = A͞C² +B͞C²
and
A͞B² = A͞C² + B͞C² is NOT wrong.
hypocrisy is bad.
If it is, then it isn't for making things wrong,
which is something hypocrisyᴿꟳ
(not.talking about outside the domain)
doesn't do.
There is no "outside" the universe.

I am more familiar with unrestricted comprehension
being the antonym of restricted comprehension.
Unrestricted comprehension grants that
{x:P(x)} exists because
description P(x) of its elements exists.
Restricted comprehension grants that
{x∈A:P(x)} exists because
description P(x) and set A exist.
The existence of set A might have been granted
because of Restricted.Comprehension or Infinity or
Power.Set or Union or Replacement or Pairing,
but A would be logically prior to {x∈A:P(x)}
by some route.
Geometry, axiomatic geometry or Euclid's,
is a classical theory, and it's constructive,
there's only expansion of comprehension,

No, "what can you think", it means.

Okay. Then you did answer my question.
"Comprehension", "construction" and "what can you think"
each seem to me very different from the other two.

It is not wrong, when talking about certain things,
to not.be.talking about other things.
It is not wrong, it is not possible to do otherwise.
There is no pair of integers in the ratio of √2
To say that
there are pairs of reals in the ratio of √2
does not argue against the first claim,
because they are claims about different things.
To pretend that it argues against the first claim
is wrong.
