Table of n, a(n) for n=1..66.

E.g. Pi=3.14159... whose decimal places begin with 1, so it is the first term in this sequence. Pi^2=9.869... begins with 8 so a(8)=2. a(14)=1 because Pi=3.14...

Sequence in context: A021089 A154194 A091589 * A094961 A069814 A198816

Adjacent sequences: A100319 A100320 A100321 * A100323 A100324 A100325
