The convention 0^0 = 1 was applied in computing the terms.
There are 61 values that can occur in this sequence, namely all numbers of the form x^y for some 0 <= x, y <= 9. (End)

(PARI) pistring(n) = default(realprecision, n+10); my(x=Pi); floor(x*10^n)
pidigit(n) = pistring(n)-10*pistring(n-1)
a(n) = pidigit(n-1)^pidigit(n) \\ Felix Fröhlich, Sep 23 2019
