Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

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