The Maine Indian land dispute moved to the White House yesterday as President Carter's personal representative gathered all of the hostile parties together for a preliminary meeting.

Participants said no agreements were reached at the meeting, attended by nearly 50 persons summoned by William B. Gunter, who is retiring as a Georgia Supreme Court justice.

The Penobsot and Passamaquoddy Indian tribes of Maine are suing for land they claim was taken illegally from them in violation of 18th Century treaties. Their initial suit claimed more than 12 million acres and companion for years of trespass.

Yesterday's meeting was the first including all of the parties. Attending were Maine Gov. James Longley, the Maine congressional delegation, representatives of the Indian tribes and officials of the Departments of Justice and Interior.

Gunter intends to submit a report to President Carter who in turn is expected to recommend a settlement to Congress. Gunter told the group yesterday he expects to meet within two weeks with their Representatives to begin discussions of specific issues.

Gunter is expected to make his recommendations before June 1, which is the deadline set for the Justice Department to go to court to present the Indian claims. A federal judge in Maine ordered Justice to represen* t the tribes.
