Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 20 points:

(2,4)(5,6,9,10,8,11,7,12)(13,14,18,19,17,15,16,20);(6,10)(7,9)(11,12)(13,15,18,20,17,14,16,19);(1,2,3,4)(5,7,8,9)(6,10,11,12)(13,16,17,18)(14,19,15,20);(6,11)(10,12)
