# CHANGES to the 'primgrp' GAP package

## 4.0.1 (2025-09-25)

  - Add `PrimitiveGroupsAvailable` to the manual (it has been around
    for a long time but we forget to link it up there)
  - Fix `PrimitiveGroupsAvailable` for degree 4096 to 8191 to return `false`
    if the extra data set is not installed

## 4.0.0 (2024-12-06)

  - Add support the primitive groups of degree 4096 to 8191; these
    must be downloaded separately, see README.md for details
  - Add Jesse Lansdown as package author
  - Stop using `InstallValue`

## 3.4.3 (2022-12-10)

  - Fix inconsistencies in `COHORTS_PRIMITIVE_GROUPS` in degrees 1550 and 1575
  - Fix socle type for natural An/Sn in degree >= 2500
  - Ship data files compressed to save disk space
  - Update some links
  - Minor janitorial changes

## 3.4.2 (2022-05-03)

  - Unify notation for names that involve Mathieu groups to use
    M(n), instead of a mix of M(n) and M_n
  - Fix the name of PrimitiveGroup(81,103) [Reported by Andries Brouwer]
  - Fix the names of PrimitiveGroup(i,j) for (i,j) in
    { (100,14), (121,38), (289,35) }
  - Rename PrimitiveGroup(960,7) from OPlus(8, 2) to O+(8, 2)
    to be consistent with all other groups related to O+ or O-
  - Fix names of PrimitiveGroup(1600,i) for i in [17..19]
  - Fix PrimitiveGroup(1140,2) wrongly named Sym(40) instead of Sym(20)
