1619edo is excellent in the 13-limit. It supports an extension of the [[Ragismic family|ragismic]] temperament with 2 extra dimensions in several ways. First, it supports the 441 & 270 & 1619 rank-3 temperament tempering out [[4225/4224]], [[4375/4374]], [[123201/123200]], 655473/655360, 1664000/1663893, and 6470695/6469632. Second, it supports 72 & 494 & 270 & 1619 temperament tempering out [[6656/6655]], 2912000/2910897, and 29115625/29113344.  
1619edo is excellent in the 13-limit, where it tempers out [[4225/4224]], [[4375/4374]], [[6656/6655]], 78125/78078, and 117649/117612. It also notably tempers out [[123201/123200]]. It supports [[vidar]], which has the comma basis 4225/4224, 4375/4374, and 6656/6655, and other unnamed expansions of the [[ragismic]] temperament such as the 270 & 441 & 1619, tempering out 4225/4224, 4375/4374, 655473/655360, or the 72 & 270 & 494 & 1619 temperament tempering out 6656/6655 and 2912000/2910897.  


In general, 1619edo supports vidar, with the comma set 4225/4224, 4375/4374, and 6656/6655.
1619edo has 7/6 on 360th step, a highly divisible number, 27/25 on 180th, and 33/32 on 72nd as a consequence of tempering out the commas. This means that 72ed33/32 is virtually equivalent to 1619edo. When it comes to using 33/32 as the generator, 1619edo supports the 832 & 1619 temperament, which tempers out 196625/196608, 200000/199927, 2912000/2910897, and 3764768/3764475.
