Ty for notifying me. I am just getting started with APL so I don't even know what I don't know yet
OK, well, I can definitely help you if you want my help.
I can offer to teach you right here in chat, point you at self-study materials, show you the community, etc. etc.
I've got very little time tonight, but I may take you up on that sometime. I'm about to go to bed, though. I hope you have a good night/day
Sleep well. I'm usually here, so feel free to ping me (@Adám) whenever.

@Adám Ah, so you reverse even less. Nice.
I just found a completely different approach that is much faster than H. −86% for n=1000.
You have a truly marvelous demonstration of this proposition that this margin is too narrow to contain?
No, actually, my new function is about two thirds the length of the previous fastest: '⎕'/⍤1⍨⍳(-,⍤0⊣)⊢

Ah, thought there might be something good with replicate!

@Adám I've got more time now for reading and learning and would greatly appreciate recommendations. I've currently got very little experience in programming, and am following Rodrigo's APL Corner, specifically learning APL with Neural Networks.

@PurpleClover42 No worries. APL Wiki actually has a whole section of learning resources just for non-programmers.
