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]

[math]\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. }[/math]

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]
