Input: Consider Input: Passage: In 1948, Alderman Fred Henderson, a former mayor of Norwich who had been imprisoned in the Castle for his part in the food riots of 1885, proposed a memorial to Kett. Originally hoping for a statue, he settled for a plaque on the walls of Norwich Castle engraved with his words and unveiled in 1949, 400 years after the rebellion. In the 21st century the death of Kett is still remembered by the people of Norwich. On 7 December 2011, the anniversary of his death, a memorial march by members of Norwich Occupy and Norwich Green Party took place and a wreath was laid by the gates of Norwich Castle.
Question: How many years was Alderman Fred Henderson imprisoned before proposing the memorial to Kett?

Input: Consider Input: Passage: The Front refused to officially disclose the number of members that it had. Thurlow suggested that "the most reliable estimates" were those produced by the anti-fascist investigatory magazine Searchlight (magazine). Following its establishment, the NF claimed to have 4000 members in 1968, and in February 1974 a branch chairman claimed that it had 20,000 members. Fielding suggested that it probably had about 21,000 members in early 1975, of whom 6,000 to 8,000 were "paper members" who had not renewed their membership subscriptions but not officially terminated their membership. Searchlight claimed that from its origins with 4,000 members in 1968, the party reached a peak membership of 17,500 in 1972, which had declined to 10,000 in 1979, to 3,148 in 1984, and to 1,000 in January 1985. An estimate of party membership in 1989 put adherents of the Flag Group at about 3,000 and of the Strasserite faction at about 600. Thurlow noted that even at its peak in the 1970s, the Fronts membership was still only half the size of that of the BUF during its 1930s heyday.
Question: What group was twice as large as the Front?
