1,1

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

Table of n, a(n) for n=1..27.

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.

Cf. A261158 for the English variant.

Sequence in context: A258502 A011019 A254979 * A193728 A295582 A192424

Adjacent sequences: A261154 A261155 A261156 * A261158 A261159 A261160
