A visual study of the Icosahedron inside an Octahedron - and the remaining tetrahedral modules

The tetrahedral modules:

Buckminster Fuller came up with these modules and called them "S modules" or "S quanta modules".

Here is a helpful summary:

[ENG TRANS] GNJB - If we were a novel

[Jun]

I wonder if it’s still empty beside you 

But it’s not like you have to tell me,

[Kazuto]

Looking back now, well, I’ve been going out too much

Because the answer to that question might just break me

[Kaname]

Everywhere I go,

[Kousaku]

it’s all my memories with you, I’m sick of it

Surely, if this story were a novel, 

This city has become such a hard place to live in. 

[Takato] 

And the end roll where we end up together awaits us

Then this would just be another twist in the plot, 

[Masaya]

Though it will never happen

[All]

The most trivial memories keep spilling out

[Ryota]

Though I didn’t properly bookmark the pages of our moments,  

It’s so easy to find traces of you, you’re everywhere.

[All]

I end up remembering it at once

I understand perfectly what the word “goodbye” means. 

[Jun]

I could just fall in love with someone else,  

And yet today, for some reason, my heart still doesn’t. 

[All]

but I’m such a fool, aren’t I?

Inside the painted white lines,  

That I’m still searching for you. 

[Kazuto]

Two shadows stood side by side,  

It felt like I'm looking at us back then,  

Connected with no boundaries 

[Kousaku]

Surely, if this moment were a novel,

And once again, I remembered you. 

[Kaname]

And yet, you walk away,  

This would be the part where things get interesting. 

[Takato]

Leaving the helpless me behind.  

If you were going to leave anyway,  

You’re so unfair, really. 

[Ryota]

You could’ve at least made me hate you first before you go. 

[Jun]

Learning from the ending,  

Now I’m the one still chasing the shadow of your back from that day. 

[Kousaku]

I know you won’t be anywhere in the pages ahead.  

If that’s the case,  

Left unwritten, untouched,  

Then none of it even matters anymore. 

[Masaya]

I can only look back at what once was.  

Even if these words are too clumsy to say it as afterword,  

How many more seasons will I have to endure like this? 

[Jun]

After all, I still love you

[All]

The most trivial memories keep spilling out

[Takato]

Though I didn’t properly bookmark the pages of our moments,  

It’s so easy to find traces of you, you’re everywhere.   

[All]

I end up remembering it at once

I understand perfectly what the word “goodbye” means.  

And yet today, for some reason, my heart still doesn’t.  

I could just fall in love with someone else,  

but I’m such a fool, aren’t I?

That I’m always searching for you.

Pentagonal Icositetrahedron:

Also called the Pentagonal Icosikaitetrahedron

Catalan Solid

Dual of the Snub Cube

It has 24 irregular pentagonal faces, 60 edges, and 38 vertices of three types.

Chiral so it has two forms that are mirror images of each other.
