801 (eight hundred and one) is the natural number following 800 and preceding 802.

801 is the sum of a square and positive cube in more than one way, and a sum of distinct positive cubes in more than one way:[1][2]

${\displaystyle 801=17^{2}+8^{3}=26^{2}+5^{3}=1^{3}+2^{3}+4^{3}+6^{3}+8^{3}=2^{3}+4^{3}+9^{3}.}$

In the gematria of 2nd century bishop Irenaeus, 801 stands for both the Greek word for a dove, and for Alpha and Omega, and therefore represents God in two ways.[3]
