The number 360 is centered across the 360th decimal place of π:
6998970 = 36 + 19 + 49 + 18 + 59 + 97 + 20
6998971 = 36 + 19 + 49 + 18 + 59 + 97 + 21
(Thanks, Pablo.)
The 22nd, 7th, 355th, 113th, and 52163rd digits of π (counting from the 3) are 2s.
The 16604th digit, alas, is a 1 — but it’s flanked by 2s.
