[seqfan] Neusis construction - A122254/A048136 with/out 11,22?

[Georg.Fischer]

Hi Seqfans,

<https://en.wikipedia.org/wiki/Neusis_construction#Use_of_the_neusis>
cites "modified versions" of
   A122254 Numbers with 3-smooth Euler's totient (A000010)
   1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, 14
and the complementary
   A048136 Tomahawk-nonconstructible n-gons.
   *11, 22*, 23, 25, 29

and they refer to a publication from 2014 where
Benjamin and Snyder prove that the 11-gon (and hence
the 22-gon) can also be constructed with neusies (cf.
the links below).

I was tempted to change both sequences right away,
but I should better ask the mathematical gurus
before:

- Are 3-smooth Euler's totient, neusis and tomahawk
   construction equivalent?
- Is it reasonable to move 11 and 22 from A048136
   to A122254, and to augment the comments, or
- Should our 2 sequences be copied to new ones, and
   Wikipedia be changed accordingly?
