Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 32

A minimal faithful permutation representation — 5 generators on 20 points:

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