Start with a(0)=3; other terms are formed from triples of successive digits in the decimal expansion of Pi.

This sequence can be considered as a (pseudo)random generator with range 0..999. Its scatterplot graph is very similar to that of other random generators, e.g., A096558. - M. F. Hasler, May 14 2015

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

			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.
