Abstract
We develop techniques to compute the cooperations algebra for the second truncated Brown–Peterson spectrum . We prove that the cooperations algebra decomposes as a direct sum of an –vector space concentrated in Adams filtration and an –module which is concentrated in even degrees and is –torsion-free. We also develop a recursive method which produces a basis for the –torsion-free component.
