[kvxykxpi] 2D byte jump

There are 253 lattice points within a circle of radius sqrt(81.5) centered at the origin.  These can be represented by 1 byte.

OEIS A057961

Motivation is for a graph or maze among lattice points with very high connectivity.

There are 25 lattice points within a radius of sqrt(8.5).  (Despite the threshold being a circle, this ends up being a 5x5 square, because 2^2 + 2^2 = 8 < 9 = 3^0 + 0^2.)  These could be represented by a letter.
