サンプルコード

process.stdin.resume();
process.stdin.setEncoding('utf8');


var r = 100;
var n2 = 5;
var n3 = n2 + 1;
var n4 = n2 + 2;
var n5 = n2 + 3;
for (let j = 0; j < n4; j++)
{
	let d = Math.sin((j / n3) * Math.PI)
	let y = Math.cos((j / n3) * Math.PI) * r
	for (let i = 0; i < n4; i++)
	{
		let x = Math.cos((i / n3) * Math.PI * 2) * r * d
		let z = Math.sin((i / n3) * Math.PI * 2) * r * d
        console.log("p", x, y, z);
	}
}
for (let j = 0; j < n3; j++)
{
	for (let i = 0; i < n4; i++)
	{
		var b = i + j * n4 + 1;
		if (b == 42) 
		    n5 = n4;
		console.log("s", b, b +  1, b + n4, b + n5);
	}
}
