Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 30 points:

(7,8,11,13)(9,14,10,12)(15,16,20,19)(17,18,21,22)(23,24)(25,28)(26,29)(27,30);(7,9)(8,12)(10,11)(13,14)(15,17,20,21)(16,18,19,22)(23,24,26,29)(25,28,30,27);(4,6)(8,13)(9,10)(16,19)(17,21)(23,25,26,30)(24,27,29,28);(7,8)(9,14)(10,12)(11,13)(15,18)(16,17)(19,21)(20,22)(23,25)(24,28)(26,30)(27,29);(3,4)(5,6)(7,10,11,9)(8,12,13,14)(15,19,20,16)(17,18,21,22)(23,24)(25,28)(26,29)(27,30);(1,2)
