Does anyone know what this symbol is, or where I can find out? I found this necklace at my grandma’s house, and have no idea what it is. It may actually be nothing, but I thought I’d see if anyone in the Tumblr world could help me out. It looks kind of like a cross between a Fleur-de-lis, an Ankh, and an Anchor. 

The pictures are a bit blurry, but they were the best I could do being so close. If you know anyone who might know, feel free to pass it along. If the symbol has any meaning, I’d like to find out what it is.

[ Abstract ]
It shown that the five Regge transformations act as a spectrometric splitter on any 6-j symbol. Four unknown partitions are brought out: S4(0), S4(1), S(2) and S4(5). They are stable subsets, with well defined parameters depending only on triangles and quadrangles. These findings are easily generalized to super 6-jS symbols, properly labelled by their own parity alpha, beta, gamma. Super Regge symmetry is reduced only for beta where S4(2), S4(5) vanish. In addition, all tools for computing exact values of any 6-jS are provided.
