''The whole thing, the inauguration and this,'' he said, ''is a happening. It's an ace.''

Last year, more than 100 million Americans watched the Super Bowl, which has often drawn the largest television audience of the year.

The Inaugural Committee official said Mr. Deaver had ''embraced'' the idea of asking the N.F.L. and ABC to include Mr. Reagan in their Super Bowl broadcast.

Several parties also said that Mr. Deaver suggested, through the Inaugural Committee, that ABC, which has the right to broadcast the game this year, televise the game's national anthem from a ceremony in Washington at which President Reagan and Vice President Bush will be present.

Discussions About Anthem

Mr. Weiss said Robert Janni, a producer of football half-time shows and spectacles who is helping plan the inaugural festivities, had approached him about having the anthem broadcast from Washington.

''My first contact was with Janni,'' he said, ''and last Friday I had a discussion with Ron Walker, the chairman of the Inaugural Committee.''

Mr. Weiss said Mr. Walker had made it clear that Mr. Deaver was ''very enthusiastic'' about the plan.

''If the President were interested in participating in the coin toss,'' Mr. Weiss added, ''I'm sure we'd be happy to work it out.''
