Éric Angelini, The a(n)th digit of S is present in a(n), SeqFan list, Nov 20 2014.
EXAMPLE
a(1) = 1 is contained in A247143(1) = 1;
a(10) = 1 is contained in A247143(10) = 10;
A(100) = 7 is contained in A247143(100) = 78;
a(1000) = 5 is contained in A247143(1000) = 885;
a(10000) = 5 is contained in A247143(10000) = 9656;
a(100000) = 2 is contained in A247143(100000) = 101207;
a(1000000) = 1 is contained in A247143(1000000) = 1000061.
