Pi written in base 2 is 11.0...[2] so "10" occurring at position a(2) = 0 (digits corresponding to 2^0 and 2^-1) is the first permutation of the digits 01 to occur in the digits of Pi written in base 2
3: [2,
Pi written in base 3 = 1.00102...[3], so "102" occurring at position a(3) = 3 (the string starts at the digit corresponding to 3^-3) is the first permutation of digits 012 to occur in the digits of Pi written in base 3.
Pi written in base 4 is 3.021...[4], so "3021" occurring at position a(4) = 0 (the string starts at the digit corresponding to 4^0) is the first permutation of digits 0123 to occur in the digits of Pi written in base 4.
Pi written in base 5 is 3.0323221430...[5], so "21430" occurring at position a(5) = 6 (the string starts at the digit corresponding to 5^-6) is the first permutation of digits 01234 to occur in the digits of Pi written in base 5.
Pi written in base 6 is 3.0, 5, 0, 3, 3, 0, 0, 5, 1, 4, 1, 5, 1, 2, 4, 1, 0, 5, 2, 3...[6], so "102" occurring at position a(6) = 15 (the string starts at the digit corresponding to 3^-3) is the first permutation of digits 012 to occur in the digits of Pi written in base 3.
Pi written in base 7 is 3.06636514320...[7], so "6514320" occurring at position a(7) = 5 (the string starts at the digit corresponding to 7^-5) is the first permutation of digits 0123456 to occur in the digits of Pi written in base 3.
Pi written in base 8 is 3.11037...(360 digits omitted)...6253510756243...[8], so "10756243" occurring at position a(8) = 371 (the string starts at the digit corresponding to 8^-371) is the first permutation of digits 01234567 to occur in the digits of Pi written in base 3.
Pi written in base 9 has the first string of 9 distinct digits, "352710468", starting at position a(9) = 742.
Pi = 3.141592653589793238462643383279502884197169399375105820974944592307816... in base 10) has the first string of 10 distinct digits, "4592307816", starting at position a(10) = 60.
