cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

Better definition from Franklin T. Adams-Watters, Apr 10 2006

A098711 Write down decimal expansion of Pi; starting with 31, divide up into chunks of minimal length so that chunks are increasing numbers and do not begin with 0.

Seems to grow slower than A016062 (another sequence built on the same principle, which begins with 3, 14, 15, 92, 653...).

Examples

			a(4) = 265, the three digits of Pi following a(3) = 59, because neither 2 nor 26 is > 59. a(13) = 75105820 even though 7510582 > a(12), because a(14) may not begin with a 0.
