Part of my plan for fixing my minimax calculations involves using
rational arithmetic, so I'm interested in ets in other limits which correspond, more or less, to 103169 in the 7-limit. This isn't an actual requirement, but it seems better style.

If anyone has done similar computations this far out in the 11 and 13 limits, could you post the results here? I'll defend you from the charge that such computations are useless by way of payment.
