The first digit of Pi is 3, indicating a(1) consists of the next 3 digits: 141. The next digit of Pi is 5, indicating a(2) consists of the next 5 digits: 92653, etc.
If the run digit is a sequence of N zeros, then the run length is the next N+1 digits following the zeros. For example, after a(12) the next digit is a zero. The run length is the next two digits, 78, so a(13) is a 78-digit number: 164062862089986280348253421170679821480865132823066470938446095505822317253594.
a(222) is the first 3-digit run at 971 digits.
a(318) is the first 4-digit run at 4229 digits.
