Magma scripts (unsorted, devel)

I am providing here several scripts I am using in my computations with Magma. Some of them are planned to be included in a regular package for this computational algebra system. The provided scripts are in early development stage and usualy not well-commented. Thus, the linked files may be updated in time. Please check timestamps in headers of respective files. Please note that functions/procedures with names ".+Old" are deprecated and shall not be used, they left in script files just for author's convenience and reference. Some of these scripts or particular functions were developed with help from other persons e.g. M. Conder, A. Mednykh, R. Nedela, M. Škoviera, and others.

List of scripts

  • mapfuns.mag - several functions and procedures for computations with orientable maps.
  • cnils.mag - properties of special nilpotent groups, just one-purpose script.
