It has a number: op
It has a weight: qr.845 (roughly)
Change any letters to digits in one of the usual ways. If the name was Fred, we would have i = 6, j = 8 ...
The cache is at N52 3a.bcd W001 0e.fgh, where
a = j + l - i
b = l + m - o
c = k + o - p
d = i + q - r
e = m + p - n
f = k + q - n
g = j + r - m
h = l + q - i
