Formula

a(n) = A001622(A277259(n)+1) * A002275(n).

Example

1205th to 1230th digits of phi are as follows: ...63972321340444494873023154...
The 1216th digit is occupied by the first of four consecutive 4's and there is no earlier occurrence of four or more consecutive equal digits, so a(4) = 4444.
