I'm confused on what grouping this is ? Is it a 32nd triplet or are they 16th triplets nested in something else ?

I'm also quite confused on how to count this mentally, aside from hearing the stabs on the 11th fret in the rhythm.
The Demon's Name Is Surveillance is the song for reference

edit: maybe should've mentioned the song is in 12/8 and a single measure has 4 of the underlined groupings.
