Question: How many seats did the Austrian legislative party first named the Communist Party of German-Austria gain in 1945?

<P0-S0> The Communist Party of Austria (German: "Kommunistische Partei Österreichs" , CPA or KPÖ) is a communist party in Austria. <P0-S1>  The KPÖ was banned between 1933 and 1945 under both the Austrofascist regime and the Nazi German control of Austria after the 1938 "Anschluss". <P0-S2>  Established in 1918 as the Communist Party of German-Austria (KPDÖ), it is one of the world's oldest Communist parties. <P0-S3>  It played an important role in the Austrian resistance against the Nazis. <SEP> <P1-S0> Onorato Damen (4 December 1893 – 14 October 1979), was an Italian left communist revolutionary who was first active in the Communist Party of Italy. <P1-S1>  After being expelled, he worked with the organized Italian left, became one of the leaders of the Internationalist Communist Party, commonly known by their paper Battaglia Comunista. <P1-S2>  The Internationalist Communist Party formally founded in 1945, was numerically the largest left-communist organization in the post-World War II period. <P1-S3>  In 1952, Amadeo Bordiga, who had by then fully came out of retirement to found the International Communist Party, known by its paper Programma Comunista. <P1-S4>  Many elements of the original Internationalist Communist Party left to join the party Bordiga had formed. <P1-S5>  Onorato Damen lead the older party that did not follow Amadeo Bordiga into the new party but rather maintained the original name Internationalist Communist Party, maintained the original theoretical journal Prometeo, and their paper Battaglia Communista. <P1-S6>  Onorato Damen was politically active his entire adult life. <P1-S7>  He was the author of "Gramsci: tra marxismo e idealismo". <SEP> <P2-S0> Party of Slovak Revival (Slovak: "Strana slovenskej obrody" , SSO) was a political party founded in 1948 by pro-Communist members of the Slovak Democratic Party. <P2-S1>  It was accepted into the Czechoslovak National Front and got 17 seats in the Slovak parliament (Communists had 78 and the Freedom Party 4 seats). <P2-S2>  Jozef Mjartan, chairman of the SSO was the interim chairman of the Slovak parliament from 15 to 23 June 1958 and the party (as a satellite of the Communist party) had representatives in other government bodies during the Communist era. <P2-S3>  The Party of Slovak Revival broke with the Communist Party in 1989, but did not gain any importance in Slovak politics. <SEP> <P3-S0> The elections to the Austrian National Council held on 25 November 1945 were the first after World War II. <P3-S1>  The elections were held according to the Austrian election law of 1929, with all citizens at least 21 years old eligible to vote, however former Nazis were banned from voting, official sources putting their numbers at around 200,000. <P3-S2>  This was highly embarrassing for the Communists, who had assured the Soviets that they could win as much as 30 percent of the vote. <P3-S3>  This proved to be the beginning of a long decline for the Communists, though they stayed in the chamber until May 1959. <P3-S4>  The Communist Party of Austria only gained four seats, which some blamed on the conduct of the Red Army in the Soviet occupied zone of Austria.
