Seventy-six is four times nineteen and reduces to thirteen and then four. It is among the integers in the seventies without traditional religious symbolism; the older systems passed it over. Its modern fame is incidental and American, the spirit of '76 of the Revolution of 1776, and the seventy-six trombones of a Broadway song, neither of which gives the number any deeper meaning.
Seventy-six factors as 2^2 x 19 and carries 6 divisors in all. Summing its proper divisors gives only 64, short of the number itself, which places it among the deficient numbers in the same classical scheme.
None of this genealogy is hidden by the numerologists themselves: Balliett, Campbell and Jordan each wrote openly as originators and systematisers rather than as transmitters of a secret ancient science, and the chain from Balliett's 1908 book through Campbell's 1931 manual to Jordan's 1965 standardisation is well documented in the numerology literature's own bibliographies.
Where the Chaldean chart and the Balliett-descended chart assign different values to the same letters, a name totalling one figure in one system need not total the same figure in the other, since the two rest on unrelated letter-value tables rather than on a shared inheritance from any single ancient source.
