A261159 List the length of chunks of letters different from 'e', when the sequence is spelled out in French: this is the lexicographically first such sequence of nonnegative integers.

5, 7, 1, 11, 2, 1, 3, 13, 2, 2, 1, 3, 12, 13, 0, 7, 3, 11, 1, 5, 41, 12, 0, 7, 1, 5, 11, 2, 1, 7

Called "Perec's sequence" by E. Angelini, with reference to Perec's 300 page novel "La disparition", lacking the letter 'e'.

			The sequence spelled out in French reads: cinq, sEpt, un, onzE, dEux, un, trois, trEize, ...
Counting the length of chunks of letters different from 'E' ("cinqs", "ptunonz", "d", "uxuntroistr", ...) yields: 5, 7, 1, 11, ..., which reproduces the sequence.

Inspired by an analogous sequence for the French language, published by E. Angelini on Facebook, see A261159.

			Spelling out the sequence in German, and counting the length of runs of letters different from 'e', yields:
zwei eins acht neun zwölf zwei neun zwölf  ...
2 |1 |    8     |     9     |      12 ...
This is again equal to the sequence itself.
