That might be an understatement of his capabilities, though obviously he wasn't a professional mathematician. It's a joy to read some of the eulogies professors at the Santa Fe Institute gave to him:

https://www.santafe.edu/news-center/news/memoriam-cormac-mcc...

> He had an encyclopedic knowledge of the world and a memory to match. Topics ranged from salvage diving — something we discussed a few days ago — to far more academic fare often focused on mathematics and physics.

> Cormac and I engaged on a wide range of topics. Some recurring themes included social mobility, machine intelligence, the intersection of genius and madness, and cars and trucks.

> Cormac also often remarked that a lively conversation with friends is about as good as sex. He’d talk for hours about physics, math, novels, philosophy, human nature, bawdy humor, corny humor, architecture (including detailed advice on my own house), gambling, history, and any question that lacked a quick and obvious answer.

Etc.

Thanks very much for posting this link. The eulogies were indeed a pleasure to read. Choked up a few times.
