The table below shows the special conditions implemented in equiv, together with the codes to be supplied with the COND card (see the Keywords section). The symbol Q means that the hkl indexes are permutable.

h or k or l = 4n | 2 |
h or k or l = 2n | 3 |
0kl: k, l =2n Q | 4 |
hhl: 2h+l = 4n Q | 5 |
h00: h=4n Q | 6 |
-h+k+l = 3n | 7 |
00l: l= 6n | 8 |
0kl, hhl: l= 2n, h+l=3n | 9 |
