Usually denoted by D30 and also called triacontahedron or triacontaeder.|
The D30 was originally the brainchild of John Handwork, a college freshman at Virginia Tech who,
in 1982, sold the idea to toy and game entrepreneur Roy Lippman of Baltimore, Maryland, USA.
He passed on the rhombic dodecahedral dice since he felt it would conflict with the existing 12 sided dice.
His company, The Armory, was a great rival to the Zocchi's Gamescience.
