Undergrad Difference Between Lorentz Transformation & Special Relativity

What exactly is the difference between special relativity and the Lorentz transformation? Reading about them they seem to be really similar.

Sorry for the extra question. Just have a lot of questions lately and I know some people around here are annoyed with that.

Special relativity is a physical theory. The Lorentz transform is a mathematical operation. Special relativity uses the Lorentz transform to make predictions about physical experiments.

Special relativity is a set of postulates regarding speed of light and inertial reference frames which forms an entire theory.

The Lorentz-transformation is a mathematical operation used to find the quantities measured in one inertial reference frame expressed as quantities measured in another inertial reference frame.

It's like asking what the difference between feynman diagrams and quantum field theory is.

The Lorentz transforms are one way of defining Minkowski spacetime. Special Relativity is the physics of being in a Minkowski spacetime. Naturally, the Lorentz transforms turn up a lot.

It's a bit like the difference between Euclidean (and spherical) geometry and cartography. You can't do much cartography without an understanding of straight lines and angles, but cartography isn't just straight lines and angles.
