How can I shorten this code?

	for(int i = 0; i < 3; i++){
    	Instantiate(Prefab, new Vector3(-3, 10f * i, 0), Quaternion.identity);
    				Instantiate(Prefab, new Vector3(3, 10f * i, 0), Quaternion.identity);
    				Instantiate(Prefab, new Vector3(1, 10f * i, 0), Quaternion.identity);
    				Instantiate(Prefab, new Vector3(-1, 10f * i, 0), Quaternion.identity);
    				Instantiate(Prefab, new Vector3(2, 10f * i, 0), Quaternion.identity);
    				Instantiate(Prefab, new Vector3(-2, 10f * i, 0), Quaternion.identity);
    				Instantiate(Prefab, new Vector3(0, 10f * i, 0), Quaternion.identity);
}

Thanks!

With a nested for loop:

for(int y = 0; y < 3; y++)
{
    for(int x = -3; x <= 3; x++)
    {
        Instantiate(Prefab, new Vector3(x, 10f * y, 0), Quaternion.identity);
    }
}

Maybe you want to multiply x also with a distance value, otherwise the objects have a distance of 1 in the x-axis
