1. Namely, it was discovered that, contrary to expectation, the symmetric metric on the quaternionic projective plane is " not " its systolically optimal metric, in contrast with the 2-systole in the complex case.
2. While the quaternionic projective plane with its symmetric metric has a middle-dimensional stable systolic ratio of 10 / 3, the analogous ratio for the symmetric metric of the complex projective 4-space gives the value 6, while the best available upper bound for such a ratio of an arbitrary metric on both of these spaces is 14.
3. It's difficult to find quaternionic projective plane in a sentence. 用quaternionic projective plane造句挺难的
