I wrote that I didn't know what "unexampled richness" means. Fred
Linton was the first to tell me that it means unparalleled. Indeed,
the Oxford English Dictionary gives the definition:
Having no preceding or similar example; unprecedented, unparalleled.
and lists 7 citations, the earliest from 1610.
Sounds like a contradiction to me.

"Even" can be dropped. There being no preceding such, 2 is an
unexampled prime.
The occasion of two centuries (to within the very month) after Boole's
birth is a most auspicious one to point out that, as a prime number, the
number of solutions of x^2 = x is unprecedented.
