Ciro Santilli 35 Updated 2024-12-23 +Created 1970-01-01A positive definite matrix that is also a symmetric matrix.
Group of even permutations.
Note that odd permutations don't form a subgroup of the symmetric group like the even permutations do, because the composition of two odd permutations is an even permutation.
One major advantage: eukaryotes can do phatocytosis due to their cytoskeleton.
