NAME

List run lengths of digits different from '1'. Lexicographically- first such sequence of nonnegative numbers with no repeated terms.

EXAMPLE

The sequence cannot start with a(1) = 0 , which would imply to start starting with a chunk of 0 digits different from '1', i.e., a digit '1': contradiction. It also cannot start with a(1) = 1 , which would require to start starting with a string of 1 digit different from '1': contradiction. So it has to start with a(1) = 2 digits different from '1'.

CROSSREFS

Cf. A261160 - A261169 for the variants which that use digit '0', ..., '9' as delimiter.

Jon E. Schoenfield: Maximilian -- You raise a good question, and I was surprised just now at how many two-word, hyphenless results I got from a brief Internet search for "lexicographically first" ....

More importantly, what I found at

     http://www.chicagomanualofstyle.org/16/images/ch07_tab01.pdf

under the section

     2. compounds according to parts of speech

-- although the rules given there are more complex for the situation

     adverb not ending in ly + participle or adjective

-- it says _not_ to use a hyphen in the situation

     adverb ending in ly + participle or adjective

(which is what we have with "lexicographically" (adverb ending in "ly") + "first" (adjective) ... so I think I was wrong.  :-(  But I do appreciate your asking, and I'll try to keep this in mind in the future!  :-)

Thanks!  -- Jon

M. F. Hasler: As usual, thanks for your expertise. But I wish to understand better/more: isn't "lexicographically" the adverb that determines the adjective "first"? Why do you suggest to glue them together? When I google "alphabetically-first", I find it mostly without hyphen...
