Presentation

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

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

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