Presentation

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

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

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