I calculated the descriptor of the mesh as follows by ShapeSymmetry.exe. image But the 5-fold symmetric descriptor I got is strange. Here is the visualization of the 5-fold descriptors. And the k-fold( k = 3、4、5、6) symmetric descriptor look the same. 34F319C8-6D09-4ecf-903E-FECC509DDC2B

Here is the visualization of the 2-fold descriptors. lQLPJw4C5RdVPErNAVrNAV-w41fvXu6DanoEq5EIDQC7AA_351_346

What's more, the peak in the descriptor could not correspond to axes of near 5-fold rotational symmetry. Do you know what the reason might be?

Would you be able to share the model?

I realized that there are different definitions of i and j between the code and comments. In the code, this is the definition of i and j. 3b10c0de09c436ad16e4753721b7cacf In the comments, this is the definition of i and j. It seems to be opposite. I wonder which one is correct? ebac0a375501559894364903af196c7e

I would guess that the code is correct and the comment is wrong.
