[seqfan] Re: Dumb, language, base dependent department

[M. F. Hasler]

More "fundamental"/simple but not yet in the OEIS:

1,4,2,6,3,7,5,...
= reorder IN* by listing the first number with English name ending
 in a vowel (A000861), first ending in a consonant (**)

just submitted : A247359 = the complement (numbers ending in a consonant) of
A000861 = 0,1,2,3,5,9,12,
= zero, one two, three, five, nine, twelve, ...
= numbers with English name ending in a vowel

see also:

A059437 & A152592
Consider the last letter of each of the English words zero, one, two,
three, four, five, ... . Write down 0 for a vowel {a,e,i,o,u } [or
"y"], 1 for a consonant.

the A059437 versions ("y = vowel") of the first three cited seq's
don't exist - worth submitting ?

other related seq's: oeis.org/search?q=consonant


(**) UPDATE: just submitted https://oeis.org/draft/A247362
= A permutation of the nonnegative integers: Interleave A000861 and
A247359, numbers ending in a vowel resp. consonant in English.

(Out of the current context it seemed natural to me to name it like
this, but of course the link with the current thread is that here the
"chunks" are reduced to single numbers.
NOTE: since this starts with 0(zerO), this is NOT the above listed
1,4,2,6,3,7,5,... which would be a permutation of the POSITIVE
integers not equal to the restriction of A247362 to IN*)

PS: for German and other SeqFans : the German (and other) analogs to
A000861 / A247359 are (probably(?)) still missing,
some French speaking SeqFan could double-check the just submitted
A247360 / A247361.
(Maybe the French is the most "interesting" variant due to
irregularites arising from names of 70...80...90... and 1000 ending in
a vowel unlike 10^6, 10^9,...)

Best,
M.
