Desired square lengths:
	default : 1

Checking inequality 1:
	 d  = 3
	|V| = 6
	|E| = 12
	Success: d|V| >= |E|

Checking self-intersection:
	Square collision distance = 166666666656318432619984285778277378193477782215698379236923 / 333333333348027356809177505006945752534300000000000000000000

	Success: starting realization non-self-intersecting

Checking inequality 2:
	sigma_min in [5611 / 5000, 1403 / 1250] ~ [1.1222, 1.1224]
	Success: sigma_min > 0

Checking inequality 3:

	Success: rho < sigma_min ^ 2 / (16 * E ^ .5)

Checking inequality 4:
	LHS NUM := sigma_min - [sigma_min ^ 2 - 16 * rho * |E| ^ .5 ] ^ .5 in [-1 / 5000, 10013 / 50000000] ~ [-0.0002, 0.0002]
