Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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