Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

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