Painted banners, hung between palm trees on the square’s south side, enumerated still more. They included the cancellation of a proposed law that would ban demonstrations, faster prosecution of those responsible for killing hundreds of protesters in January and February and trials for the Mubarak family on charges of plundering national wealth.

“Mubarak is still fishing in Sharm, as if nothing happened,” groused Hassan Ismail, 60, a housing manager. He was referring to the Red Sea resort of Sharm el Sheik, where Mr. Mubarak and his family now live — after being barred from leaving the country.

Some noted that the military had taken steps through a national referendum to bring about legislative elections planned for September and a presidential vote two months later. But to many, those actions seem driven by what the military wants.

“People are still skeptical about how this revolution is moving forward — they want to remind the army and all forces that the revolution did not end yet,” said Shaheer George, a 25-year-old independent activist.

The chants that erupted on the square included “The people want the fall of the field marshal,” referring to Field Marshal Mohamed Hussein Tantawi, the leader of the military council and another Mubarak confidant.
