Hello SeqFans,
We have a hit if a^b shows b
(with a = any integer and b = any digit).
(2019 must be read hereunder as 201^9)

The seq S begins (I guess):
S=11,26,37,46,52,55,56,57,59,66,67,69,
73,74,76,78,84,86,87,95,97,99,101,111,
115,119,121,128,129,131,136,137,138,139,
141,144,145,146,148,...

Example:
144-->14^4=38416 (hit "4")
145-->14^5=537824 (hit "5")
146-->14^6=7529536 (hit "6")
147-->14^7=105413504 (no "7" = no hit)
148-->14^8=1475789056 (hit 8")
etc.
Best,
É.
(my first 11 terms are not in the OEIS
and don't deserve it, perhaps!-)
Best,
É.
