This pendant represents the number 17 in base 1 1/2 using the "Exploding Dots
" method developed by James Tanton
as part of the Global Math Project
, and is the perfect accessory for Global Math Week!
What makes 17 interesting is that it becomes a mathematical palindrome in base 1 1/2: it's the same forwards and backwards.
Note that this is a pendant only, and does not include a chain.
This model has a bigger ring for a chain, and should work with the cable chains available from Shapeways or other chains with a <3mm clasp.
The version pictured in the hand is an older version with a smaller loop.
