With an equal protection clause, i.e., no particular number or a group of numbers can appear in the rule, is the problem solvable?

Depends on what rules you allow.

What you want to forbid is not so much mentioning specific numbers, but you want to only allow rules that have certain symmetries. Eg you can require tranlation invariance

    rule(x, y, z) = rule(x+offset, y+offset, z+offset)

to restrict the set of rules.
