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:

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

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.
