Homotopy Type of the Based Mapping Space $Map_*^{(k,l)}(\mathbb{C}P^2,BU(2))$
OK, I see your point. I might look at this again tomorrow.

Table of (integral) cohomology groups of K(Z,n)
There is a paper "Integral cohomology operations" by Stan Kochman that treats the stable case, and this agrees with the unstable case through a range. However, the answer is unpleasant. I think that all possible applications can be done more cleanly using a combination of $H\mathbb{Z}/p$ and $H\mathbb{Q}$, or sometimes by using $K$theory or complex cobordism instead.

Computer algebra system that test zero divisors in a quotient algebra
You'll need to give more information about $A$. What kind of presentation of $A$ do you have?

Does the category of Gspectra know G?
I think that if you define $R_G=\Sigma^\infty_+G$ in the most obvious way as an orthogonal ring spectrum, then ring maps from $R_{\mathbb{Z}}$ to $R_G$ biject with $G$, so $R_G$ knows $G$. However, this is not so relevant because the category of $G$spectra only determines the cofibrant replacement of $R_G$ in the category of rings in orthogonal $G$spectra; that's an extra wrinkle that one has to worry about.

Does $\mathbb C\mathbb P^\infty$ have a group structure?
If I remember correctly (which I do not guarantee), I once saw a comment by John Klein that he knew how to prove this, but he did not say how.
