46664 features in this campaign not because it has a palindromic property
but because 46664 happened to be Nelson Mandela's prison number
on Robben Island where he was held captive for 18 years.
He gave his prison number to the campaign intended
to raise funds for Aids patients in South Africa.
A quote from his speech at the benefit concert [ Cape Town, Nov. 29, 2003 ]
"46664 is a vital campaign to help outfight a tragedy of
unprecedented proportions that is claiming more lives than
the sum total of all wars, famines and floods."
Variation #11 ( from "ninedig3.htm" ) :
the equation (A–B)^C + (D–E)^F + (G–H)^I
46664 has 12 distinct solutions !
46664 = (1–4)^2 + (3–9)^6 + (7–8)^5
46664 = (1–4)^2 + (7–8)^5 + (9–3)^6
46664 = (1–7)^6 + (3–4)^9 + (5–8)^2
46664 = (1–7)^6 + (3–4)^9 + (8–5)^2
46664 = (3–4)^9 + (5–8)^2 + (7–1)^6
46664 = (3–4)^9 + (7–1)^6 + (8–5)^2
46664 = (3–9)^6 + (4–1)^2 + (7–8)^5
46664 = (3–9)^6 + (5–7)^2 + (8–4)^1
46664 = (3–9)^6 + (7–5)^2 + (8–4)^1
46664 = (4–1)^2 + (7–8)^5 + (9–3)^6
46664 = (5–7)^2 + (8–4)^1 + (9–3)^6
46664 = (7–5)^2 + (8–4)^1 + (9–3)^6
