No, I do not. For uncompressed files, strips can easily be generated at any size and I assume that they use (or are close to) the default libtiff strip size. For compressed files, the minimum strip size likely depends on compression type and parameters. Even then, libtiff could emulate smaller strips by allocating its own memory (not what you wanted to hear!).
