Manya has a stack of \( 85 = 1 + 4 + 16 + 64 \) blocks comprised of 4 layers (the \( k \)-th layer from the top has \( 4^{k-1} \) blocks). Each block rests on 4 smaller blocks, each with dimensions half those of the larger block. Laura removes blocks one at a time from this stack, removing only blocks that currently have no blocks on top of them. Find the number of ways Laura can remove precisely 5 blocks from Manya's stack (the order in which they are removed matters).
