Around the base of each pillar there is a circular string of a numbers. These numbers are all below 30 (with the exception of 93), and have a very high incidence of 10, 11, 12, 13, 14 and 17.
Glenn surmises that: The numbers at the base of the poles are repeat counts from STR loci of DNA. There is a pair for each locus. The number 93 represents '9.3', which is the third microvariant of a 9 count allele. Transcribing them with some punctuation (and a guess at which loci they represent) yields:
These loci (assuming they are correct) are the same as produced from systems such as PowerPlex 16. The order is alphabetic, for example, as given by GTLDNA Australia, ie (CSF1PO, D13S317, D16S539, D18S51, D21S11, D3S1358, D5S818, D7S820, D8S1179, FGA, PentaD, PentaE, TH01, TPOX, vWA). The meaning remains unsolved.
The loci suggest that the numbers represent the results of a genetic test conducted on a group of 8 related humans.
