[seqfan] Re: Digits of Pi in A179103 and A179104

[Charles Greathouse]

I get 4,4,3,... only for A179103; A179104 gives values 3,3,4,8,....

A179103 is "take the decimal digits of pi and substitute
0 -> 2
1 -> 3
2 -> 8
3 -> 4
4 -> 6
5 -> 2
6 -> 6
7 -> 4
8 -> 3
9 -> 3".

A179104 is "take the decimal digits of pi and substitute
0 -> 6
1 -> 4
2 -> 3
3 -> 3
4 -> 8
5 -> 3
6 -> 2
7 -> 7
8 -> 9
9 -> 5".

Both for some reason use 3, 3, 1, 4, 1, 5, 9, 2, 6, ... rather than
the more expected 3, 1, 4, 1, 5, 9, 2, 6, ... as the digits of pi.
