exponentiation error
In today's 7x7 difficult puzzle, there is a cage with 262144^ ... It will not accept the correct numbers 433 and 236. It will only accept 234 in those boxes. Am I missing something or is this incorrect?

Note that for exponentiation, the evaluation order is from right to left.

So for 2,3,4: 4^(3^2) = 4^9 = 262144
