1,1

This is apparently a faster-growing sequence than the corresponding index of n-th digit of e in the decimal expansion of Pi.

Table of n, a(n) for n=1..53.

The first three terms are the positions within e of the first three digits of Pi: at 18, 28 and 35, respectively: 27182818284590452(3)536028747(1)352662(4)...

Cf. A090898.
