The way I understood the story, to define a function on two numbers from Z/59Z I need to fill-in a table with 59*59 cells, by picking for each cell a number from Z/59Z. If 20% of it is still to be filled, then there are 0.2*59*59 decisions to be made, each with 59 possibilities.
Why not 590.2⋅592 ?

Right?
You’re right. I deeply regret the error and have amended the post. (It’s not a small error! The actual value doesn’t fit in a double-precision float!)
