Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 5 generators on 28 points:

(2,4)(5,6,10,8)(7,12,9,11)(13,14,18,17)(15,20,16,19);(5,7,10,9)(6,11,8,12)(13,14,18,17)(15,20,16,19)(22,25)(26,28);(13,15,18,16)(14,19,17,20)(21,22,24,25)(23,26,27,28);(1,2)(3,4)(5,8,10,6)(7,12,9,11)(13,16,18,15)(14,20,17,19);(5,9,10,7)(6,12,8,11)(13,17,18,14)(15,20,16,19)(21,23,24,27)(22,26,25,28)
