In the event of no EC majority, 58 House members could decide the election

Your premise is correct, but your list of States and the number of members needed is not.

It requires 60 members, including all from the green states below, all but one from the blue, and all but two from the green.

Of course the idea that those 60 would be able to get together despite complete opposition from everyone else is pure fantasy.

The absolute theoretical minimum is 34.  The quorum needed for the vote is a minimum of one Member from two-thirds of the States.

And if the other 8 needed for a quorum don't show up, there is no election, and if the result would be different if the full Congress weren't there, you can bet that those 8 wouldn't show up unless they supported the same person as the 26.
