%N Numbers A such that the square of concatenation AA is of form NNMM.
%C N and M must be of equal length, leading zeros are allowed. The corresponding values NM are in A107678.
%e 593 is in the sequence because we have 593593^2 = 352352649649; 998 is in the sequence since 998998^2 = 997997004004 (M has two leading zeros); 219374 is in the sequence since 219374219374^2 = 48125048125951876951876 (N has one leading zero).
%Y Cf. A107678, A106497.
