According to Dedekind every set {1, 2, 3, ..., n} is in correspondence

the whole set ℕ is multiplied by 2. The result covers twice the

Sort of like, "calling something that's
unknown or undefined or strange 'weird'
is, in a sense of language, like 'degenerate'".
That is to say it's stupid.
So, the "degenerate interval" of mathematics
isn't necessarily good nor bad, in the usual
vulgar sense that it's bad, and is intended
to reflect that when the prototype event of
the term-wise addition and the _carry_ bit,
_carries_, in the sense of an un-bounded
sequence that the sequence "rolling over"
is called "carry", when the otherwise
un-limited operation, here halving as
a placeholder for "the property of being
divisible as dividing into two parts",
then the notion of "degenerate" interval
is what according to deductive inference
must have been arrived at.
I.e. it so follows.
Then, not so much speaking to the massively
degenerate the dumbing-down of the feuilletons
and concepts of popular culture like the queering
of differences or such crap, there are already
words for these concepts that are under-defined
in usually the standard, because mathematics
is thoroughly explored both standard and non-standard.
