How to encode and schedule for "reorder"?

[Vivian]

Hello,

Thanks for the amazing work and codes.

I looked into the paper and codes but was confused about how you encode "reorder" schedule in the space. I have some questions.

1. In the codes I found
   reorder_space = generate_reorder_space(groups) and groups = 3 by default
   Shall I change groups equal to rlevel*slevel?

2. The configs it generated is just one dimensional, and does not match the description in the paper, i.e.,
   “reorder”: 𝑖1, 𝑗1, 𝑖2, 𝑗2, 𝑘1, 𝑖3, 𝑘2, 𝑗3, 𝑘3, 𝑖4, 𝑘4, 𝑗4 in Figure 3

Could you please explain these? Thanks.
