%N Write the primes backwards in base 10 and juxtapose their digits.
%C Also, decimal expansion of the constant 0.235711317191329213731434743595...
%C The same sequence, but with different indexing, would arise for the table whose n-th row lists the A097944(n) digits of the n-th prime A000040(n) from right to left. - _M. F. Hasler_, Oct 24 2019
